The Primary Arms SLx 1X MicroPrism is a 1x prismatic scope designed for duty and defensive use on AR-style platforms and carbines with a standard H1/T1 micro dot footprint. The ACSS Cyclops Gen II reticle goes beyond a simple dot giving shooters built-in ranging capability and a bold aiming point that stands out against any background. Green illumination spans thirteen brightness settings three night vision compatible so your reticle performs from pitch black to harsh midday sun without adjustment delays. AutoLive motion-sensing technology handles illumination management automatically powering the reticle up when you shoulder the rifle and sleeping when you set it down so a dead battery never catches you off guard. The etched glass construction means the reticle remains fully functional even without power.
